I do the same thing Jerold does with regards to looking up manuals online. Before I ever buy a kit I have already read the manual, watched some YouTube vids, and probably already discussed it on here.
Exploring the manual before you even buy the kit helps you to get to know the RC before you pull the trigger. It also allows you to see the part numbers for commonly replaced items, which you can look up to see if they are readily available.
Sometimes the manuals might have errors, and that's where YouTubers might have made a video about it. Like the Axial Ryft manual not stating or illustrating that a part was not symmetrical, which caused me about an hour delay in our build, as well as causing me the stress of dismantling and reassembling a somewhat complicated transmission 3 times before I realized my error
But I have seen first hand how some people have trouble comprehending exploded views and part drawings, so I get it. Looking at an RC car in pieces can be scary. Like some people can look at 2d drawings of a part and not be able to visualize the 3d shape, and vice versa. It's a weird right-side left-side brain thing. That's what forums are for though. To find help when you need it.
